"There were times when I was going with the threes, times when I was going with the twos, things like that," Jackson told Philadelphia Magazine's Birds 24/7 blog on Tuesday. "There was a point where I went into Chip Kelly's office and talked to him face-to-face to see what was going on with that. ...

"When I went in there, he said he expects everybody to buy into the system and do everything the right way. And if there is any little thing a player doesn't want to do, that's his way of reacting to it. The best thing I did was go talk to him instead of just sitting back and being mad."

Kelly wasn't going to just place Jackson with the starters right away. The two-time Pro Bowl pick had to show he was better than guys like Damaris Johnson, Riley Cooper and the rest. It sounds like that happened.

"Now I'm with the right group and everything is good and there's never been no problems. I just had to get a feel for (Kelly) and know what he wants and what he expects me to do," Jackson said.

The early "demotion" for Jackson is a reminder that nothing is promised under Kelly. Jackson will start this year, but he's going to have to perform well to be brought back in 2014 because he's being paid superstar money.
